The world’s quietest place

There’s a room in Minnesota that’s so quiet it becomes unbearable after a short time. The longest that anyone has survived in the ‘anechoic chamber’ at Orfield Laboratories in South Minneapolis is just 45 minutes. It’s 99.99% sound absorbent, it’s the world’s quietest place, but stay there too long and you may start hallucinating.

When it’s quiet, ears will adapt. The quieter the room, the more things you hear. You’ll hear your heart beating, sometimes you can hear your lungs, hear your stomach gurgling loudly. In the anechoic chamber, you become the sound.(via The Presurfer)
